ChangesSection of the release

When users kill running background agents (via the kill-agents shortcut), the system now sends a descriptive notification into the conversation.

Details
  • Single agent: Background agent "description" was killed by the user.
  • Multiple agents: N background agents were killed by the user: "desc1", "desc2".
  • Delivered as a task-notification mode message so the model understands context was interrupted
